The write to the port F data register is stored in the internal data latch, and if any port F pin is configured
as an output, the value stored for that bit is driven onto the pin. A read of the port F data register returns
the value at the pin only if the pin is configured as a discrete input. Otherwise, the value read is the value
stored in the register.
The port F data register is a single register that can be accessed in two locations. When accessed at
$YFFA19, the register is referred to as PORTF0; when accessed at $YFFA1B, the register is referred
to as PORTF1. The register can be read or written at any time. It is unaffected by reset.
The bits in this register control the direction of the pin drivers when the pins are configured for I/O. Any
bit in this register set to one configures the corresponding pin as an output. Any bit in this register
cleared to zero configures the corresponding pin as an input.
The bits in this register control the function of each port F pin. Any bit cleared to zero defines the corre-
sponding pin to be an I/O pin. Any bit set to one defines the corresponding pin to be an interrupt request
signal or MODCLK. The MODCLK signal has no function after reset.
Data bus pin 9 controls the state of this register following reset. If DATA9 is set to one during reset, the
register is set to $FF, which defines all port F pins as interrupt request inputs. If DATA9 is cleared to
zero during reset, this register is set to $00, defining all port F pins as I/O pins.
